The eye can be analyzed with relative ease as to both its function and its structure. A functional examination includes the capability to relocate the orbit and the response of the pupil to light and lodging.
The function of the eye might be evaluated in numerous methods. The patient might be asked to determine illuminated letter or objects of differing sizes on what is referred to as the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in several methods. Tension within the eyeball is determined by a "tonometer." In specific diseases, specifically in glaucoma, the tension in the eyeball is increased considerably.
Nevertheless, it needs to be well bore in mind that a patient with an eye issue might have other problems too. Frequently other physical conditions are main and impact the eye as a consequence. The look of the eye can inform the client and the doctor to troubles in some disruptions of other parts of the body even before other signs provide themselves.
One's dependence on sight is highlighted when one deals with a possible or momentary permanent loss of this essential sense. Thus, when restorative measures are sought, specific kinds of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some individuals are troubled with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were established to encourage decreased usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgical treatment is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgery is another form of vision correction. The only difference is that with this kind of surgical treatment, one's vision is remedied completely.
With LASIK eye surgery, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The primary function of this surgical treatment is to develop a threadlike, rounded "flap" in the cornea using a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling much better the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgery, there are still disadvantages that people must understand. Probably, the main reason why this kind of eye surgery has actually become well accepted is due to the fact that the majority of its cases had been effective.
However, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Since LASIK eye surgery involves the operation of the retina, which is among the most sensitive portions of the eye, the majority of people state that the operation can be extremely dangerous.
Simply puts, a basic error might practically cause an individual's lifetime loss of sight. It is important to consider lots of elements prior to choosing whether LASIK eye surgery is the best corrective procedure one has to undergo.
2. It is not a ideal treatment
LASIK eye surgery may remedy your vision but it does not necessarily suggest that it can provide you a twenty-twenty. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not always mean they have ideal vision as well.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not always be the perfect eye surgical treatment the method the majority of people view it
Conversely, the assessment of the structural see post part of the eye may be made in a number of ways. It must be well remembered that a patient with an eye issue may have other problems. Frequently other physical conditions are primary and affect the eye as a repercussion. The look of the eye can inform the client and the physician to problems in some disturbances of other parts of the body even before other signs present themselves.
Like its concrete counterpart, LASIK eye surgery is another type of vision correction.
